ZENAB P. CANDEE, OF WATEBIBUBY, CONNECTICUT, ASSIGNOR TO THE WATERBUBYFABREL FOUNDRY AND MACHINE COMPANY, OF WATEBBUBY, CONNECTICUT, A

FEED MECHANISM.

To all whom it may concern:

, Be it known that I, ZENAS P. Cannes, a citizen ,of the United States,residing at Waterbury, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements in FeedMechanism, of which; the" following is a specification, reference beinghad therein tothe accompanying drawings.

My invention has particularjreference to new and improved feed mechanismand esecially to so much thereof as relates to the ceding of blanks orarticles separatelyfrom a column or row of such blanks or articles.

-It is the object of thisiinvention, among other things, to provide asimpledevice by which blanksor articles, having a more or lessintermeshin engagement with each other, ma be ta en slngly from a columnof such b anks or articles and conveyed to a delivery point, such deviceto be composed of but few parts and these of such simple design thatthey may be economically constructed and readily assembled.

To these, and other 'ends, my invention consists in the feed mechanism,having certain. details of construction and combinations of parts, aswill be hereinafter de scribed and more particularly pointed out in theclaims. 1

Referring to the drawin s, in which like numerals of reference designatelike parts in the several figures;

, Figure 1 is a fragmentary side elevation of my improved invention withthe parts in the relative position occupied by them when the. blank' orarticle is in its first or initial position;

Fig. 21s a sectional view of such portion essentia to show the secondposition of the said blank or article in the sequence of movements Fig.3 is a similar view illustrating the thi-d position of the said blank orarticle; an

Fig. 4 is a sectional view of the parts,

with the blank or article delivered ready for an operation, that is, itsfourth and last positioni.

My invention is especially adapted to feed blanks or articles consistinessentially of hollow cylindrical bodies aving one solid projecting endwhich may either be Specification of Letters Patent.

Application filed June 1, 1916. Serial No. 101,199.

rounded orof other similar form, and for the purposes of illustrationsuch form of blanks or articles is shown in the drawings and describedin this specification, but however do not desireto be limited to suchform of blank or article.

It has heretofore been practically impossible to automatically feed suchblanks or articles owing to their intermeshing relation with each other,which difiiculty is increased proportionately to their length if theblanks or articles are attempted to be separated singly from a columnthereof and at an angle thereto, little or no difiiculty beingexperienced if the blanks or articles are taken singly from the columnin the same direction as they lie therein.

The invention is shown as applied to a power press, but this is only forthe purpose of illustration, as the mechanism can be applied to anyother form of mechanism as may be desired.

In the drawings, the numeral 1 designates the bed or base of theapparatus, 2 a die having an opening 4 therein of the desire shape andsize, mounted within a die ring 5 and restin against a backing block 3.

Adjusta ly secured to a fixed part by the screw 6 is a stop 7, the face8 of which is shown in line with one edge of the openin i.

ovably mounted in the bed 1 is the slide 9, having a pocket 10 in theend thereof adjacent .to said die. The means requisite for reciprocatingthis slide are not material, to this invention and are not thereforeherein shown.

Secured to the bed or base tie a, bracket 11, within which the tubeholder 12 is pivotally connected bythe pintle 13. A spring 15 connectedto a screw 16 in said tube holder and to a fixed for moving said tubeolder in one direction, which is'limited by the stop screw 14 threadedin said bracket 11 and upon which is the am nut 18.

T e means for conveying the blanks'or, articles from the hop er, orother source of supply to the tube holder 12 are herein shown as aflexible tube 19, the lower end of which projects into the tube holder11. sufiicient distance to; providesupport therefor. In operation, thearticles ass throu h this flexible tube sub tantia ly the re a.-

: mounted member to tive position shown in Fi 1, the rounded end'of oneblank or artic e projecting into the open end of the article just belowit.

When the slide 9' is in such position that the pocket 10 therein isbelow the tube holder 12, one of the blanks or articles, designatedherein by the numerals 20,, drops from the tube holder into said pocket.The slide now begins to move toward the die, and while the blank orarticle 20 is assuming the position shown in Fig. 2, it rocks againstthe rounded end of the blank or article 'next above it. As the slidecontinues its forward movement the tube holder 12 rocks upon the pivotmounting 13 and permits the blank or article to become disengagedtherefrom, the then position of the tube holder and the relativeposition of the two lower articles in the column being shown in Fig. 3.The slide 9 continues its movement until the article is brought intocontact with the face 8 of the stop .7, when it registers with theopening in the die 2, and either drops therein by gravity or by theaction of the tool (not shown) that is moved into position to engage it.At the same time the spring 15 returns the tube holder 12 to itsoriginal position against the stop screw 14 andmnother blank or. articledrops into the pocket 10 when it registers There are minor changes andalterations that may be made within my'invention, aside those hereinsuggested, and I would limit myself. to the exact construction hereinshown and described, except as defined by the ap pen'ded claims.
